Substitutional Impurities in PPV Crystals: An Intrinsic Donor−Acceptor System for High V OC Photovoltaic Devices

Defects are usually present in organic polymer films and are commonly invoked to explain the low efficiency obtained in organic-based optoelectronic devices. We propose that controlled insertion of substitutional impurities may, on the contrary, tune the optoelectronic properties of the underivatize...
